在此处输入图像描述我想为线性布局声明这种类型的复选框并获取每个复选框 id 以及选定和未选择的值
这种类型的复选框值得到

for(l=0;l<listCheckbox.size();l++)
                       {                    
 CheckBox edtCheckbox = (CheckBox)llremo.findViewById(l);
         boolean checked=edtCheckbox.isChecked();
                           if (checked)
                           {  
                               Log.i("was checked",edtCheckbox.getText().toString());
                               strchekBocname=edtCheckbox.getText().toString();
                               Log.v("strchekBocname checkbox post string", strchekBocname);
                               maparray.put("Value", strchekBocname);   
                               listaddalldatofform13formValue.add(strchekBocname);

                           }
